Recently I am researching about TRANSITION-METAL-FREE; CARBON-DIOXIDE; MEDIATED CARBOXYLATION; CO2; PALLADIUM; CARBONYLATION; FUNCTIONALIZATION; ARYLPYRAZOLES; LACTONIZATION; ACTIVATION, Saw an article supported by the MEXT, JapanMinistry of Education, Culture, Sports, Science and Technology, Japan (MEXT) [15H05800, 17H06143]; ACTC from JSTJapan Science & Technology Agency (JST) [JPMJCR12Y3]; JSPSMinistry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of Science. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Saitou, T; Jin, YH; Isobe, K; Suga, T; Takaya, J; Iwasawa, N. The CAS is 103-25-3. Through research, I have a further understanding and discovery of Methyl 3-phenylpropionate. Formula: C10H12O2
The Rh-catalyzed direct carboxylation of alkenyl C-H bonds was achieved by using pyrazole as a removable directing group. In the presence of 5 mol% RhCl3 . 3H(2)O, 6 mol% P(Mes)(3), and 2 equiv. of AlMe2(OMe), the alkenyl C-H bond of various alkenylpyrazoles was directly carboxylated in good yields under CO2 atmosphere. Furthermore, several useful transformations of the pyrazole moiety of the product were achieved to afford synthetically useful carboxylic acid derivatives in good yields.
